Well several things really. Where have they been stored. What is the state
of the toner, could damp have got in? The drum is often part of the toner
cart so try a new one. The corona wires can and do get corroded as well and
of course the high voltage generator could have been compromised by damp or
merely by deterioration of capacitors in the power supply.

2 laser printers have sat unused for about 1 & 2 years. Both printed
flawlessly. On re-use they both have abysmal & unusable print quality, the
contrast is shot with grey patches all over the place. Is this normal in
this time frame? Or must it be due to chemical exposure?
